3 cases: having dad's gene or mom's gene or both

This isn't a case of separated genetics. This is a case of a merged genetic value.
Expect adult familial height to be:
boys: dad + (mom + 5") / 2
girls: (dad - 5") + mom / 2
If you based it on a separate genetic analysis, you'd have to use simpler terms than exact measure such as "tall" "average" "short"
We could then apply a Punnett Square Model to the problem if we assumed that they were dominant in the order presented. If that were the case we'd also have to know if dad had the recessive "average" or "short" gene. Since we don't know, let's assume that dad is homozygous tall and mom is homozygous short.
TT + SS = 100% TS which is heterozygous tall or "all offspring will be tall but their children could be short"
If dad were heterozygous tall (TS) then we would have a 75% chance of heterozygous tall and a 25% chance of homozygous short. Including the average variable would give us a chance of two heterozygous average and two heterozygous tall. No short but the gene would still be there to be passed later.
We know though from observation that this model doesn't work in practice. The familial predictive stature model (above) seems to be the most accurate predictor with few exceptions.

There is no definite height that the daughter will be and it certainly doesnt depend on whether she gets the dads genes or the moms. My speculation would leave me to believe that the daughter will be around 5'6" because my parents are exactly those dimensions you mentioned and my sister turned out 5'7".

The mid parental height is calculated in males, by adding 7cm to the mean of parental heights; in females by subtracting 7cm. This gives the height expected at 18 years for the child,
This can normally vary by two standard deviations, or 5cm each way.
add both heights divide by two and add subtract 7 cms

No telling! I also have a brilliant kinfolk. a number of my cousins are taller than the two their mom and dad. a number of my cousins are shorter than the two their mom and dad. some are smack between. specific, it is all genetic, yet who's to assert she'll land up with great-grandma Iris' genes or Uncle Joe's genes?
